This might be heat related. You put the receiver in radio mode, the tuner gets power, volume is normal (I assume). Then a component gets overheated, volume drops. (This is just making assumptions from your description.)

Questions:

Is volume normal at all other times? When you operate tape/ phono/ cd?

Is volume normal when first powered up? After hours of operation?
 

Volume that cuts out after warm is usually an IC or transistor. You could put an ice cube in a double ziplock bag to seal the moisture then hold the cube against the body of each IC
or transistor to see if volume cuts back in. As Brad is saying, you can narrow the possibilities by figuring out what devices DO work normally.
